Exclamation 2005 XC70 radiator cooling fan won’t turn on.

Hi,
My radiator fan stopped working. Car is overheating, gauge is always at 12 o’clock . As soon as The coolant starts rising I turn off the car. I had got to boiling point and gauge never moved from 12 o’clock.
I recently got a message on dash. “ reduced engine performance” other messages are “engine system service required. 🤷🏻‍♀️ it has low power can’t pick up speed. If I release the gas peddle sometimes it will kick in and go faster. 🤦🏻‍♀️ the gets stuck for a few seconds when I try to turn it in and the gear shifter take a while before I can put it in gear. I have old motor oil and transmission oil, I need to change the oils . I replaced the parts listed below

1. replaced thermostat housing with sensor
2. Replaced radiator fan motor . “used fan motor in good working condition”
4 replaced electric cooling relay

The fan still didn’t turn on.

I don’t know what else to check. I bought a water pump but don’t know how to put it in and don’t have timing belt. I’ll replace that as soon as I can. I have not
Does anyone know what I need to check that leads to the radiator fanoii op loop or does anyone have any idea why It won’t turn on. I’m stumped. 🤔 please help. I’d appreciate the help. TIA
